Answer the following questions using the infol mach provided in this chapter. 1. True or False?An HV battery produces significantl less electricity than a 12-volt lead-acid battery wher both are connected to a hybrid vehicle's ; electric circuits. 2. A 12-volt automotive battery installed in a conventional vehicle has all of the following characteristics except __ (A) it produces direct current (B) it stores electricity (C) it is an electrochemical device (D) it recharges whenever the vehicle's engine is turned off

1. **False.** An HV battery produces significantly *more* electricity than a 12-volt lead-acid battery when both are connected to a hybrid vehicle's electric circuits. The HV battery powers the electric motor(s) which requires much higher voltage and current than the 12V system.<br /><br />2. **(D) it recharges whenever the vehicle's engine is turned off.** A 12-volt battery recharges when the engine is *running* (and in some hybrids, through regenerative braking). It does not recharge when the engine is off.<br />
